How to make this Cordova iOS plugin works in Capacitor?

[bruceli]

We've used a push notification Cordova plugin for both Android and iOS platform in a Ionic Cordova app before. Now we are developing a new app with Ionic and Capacitor, now the plugin for iOS doesn't work anymore.

The plugin can be found at: https://github.com/log2c/cordova-plugin-log2c-aliyun-push

The error is occurred when launching the app, at line 25 of file AppDelegate+AliyunPush.m.

@implementation AppDelegate (AliyunPush)

+(void)load{
    Method original, swizzled;
    original = class_getInstanceMethod(self, @selector(init));
    swizzled = class_getInstanceMethod(self, @selector(swizzled_init));

    method_exchangeImplementations(original, swizzled);
}

- (AppDelegate *)swizzled_init
{

    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(createNotificationChecker:)
                                                 name:@"UIApplicationDidFinishLaunchingNotification" object:nil];  <--- runtime error

    return [self swizzled_init];
}

Below is the error message：

EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

Why is this error and how to fix it?

Thanks!
